The heating and cooling of 2D electrons at low temperatures
A. K. Jain, J. T. Nicholls, S. N. Holmes +4
We present measurements of the cooling length for hot electrons in a GaAs-based high mobility two-dimensional electron gas (2DEG). The thermal measurements are performed o…

Probing Fermi surface parity with spin resolved transverse magnetic focussing
M. J. Rendell, S. D. Liles, S. Bladwell +6
Measurements of the Fermi surface are a fundamental technique for determining the electrical and magnetic properties of solids. In 2D systems, the area and diameter of the Fermi su…

Coulomb sensing of single ballistic electrons
J. D. Fletcher, W. Park, P. See +6
While ballistic electrons are a key tool for applications in sensing and flying qubits, sub-nanosecond propagation times and complicated interactions make control of ballistic sing…
